Tawnia Weiss BioI have been in the crane industry for over 16 years. I started my career with Compu-Crane, which at the time was the most innovative lift planning program available. In 2008 my company launched 3DLiftPlan.com with Link-Belt at ConExpo. 3DLIftPlan.com has become the most widely used lift planning program in the world. Our site sponsors are Link-Belt, Manitowoc and Tadano Mantis.
